SECTIONAL GUN Specification of Letters Patent.

Application filed March 23, 1918. Serial No. 224,102.

citizen of the United States of America, re-

siding at New York city, county and State of New York, have invented certain new and useful Improvements in Sectional Guns, of which the following is a full, clear, and exact description.

This invention relates to improvements in guns or cannons, the object being to provide a gun consisting of separably connected sections, whereby the gun can be taken apart for transportation or storage. One of the advantages of my invention is that a comparatively large gun can be produced having a maximum amount of strength, to resist bursting, with a minimum amount of weight. The guns will be made up of standardized parts, and hence a gun can be assembled on a battlefield out of the uninjured parts of a gun that has become useless through constant firing or partly destroyed by bursting shells. Any part or member of my improved ordnance or cannon can be readily replaced, should a member become unfit for use. For instance, should the rifling of the barrel become plugged through constant use, a new barrel can be readily inserted. Extra parts can be carried to replace parts that have become destroyed. My improved gun or cannon will be found especially desirable for use in the mountain regions, which present dilficulties to the transportation of large guns, as it can be taken apart and the parts thereof divided among several. carriers, such as wagons or the like. It is also well adapted for use on submarine vessels or chasers, and provides other advantageous features resulting from the construction which will be hereinafter set forth.

I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawings, forming part hereof, wherein Figure 1 is a side elevation of the barrel of a cannon made in accordance with my improvements Fig. 2 is a plan view of a different form of my improvement;

Fig, 3 is a plan view of still another embodiment of my improvement;

Fig. 4 is an end view thereof, looking from the left in Fig. 3;

Fig. 5 is an enlarged cross sectional view,

the section being taken on a line 5-5 in Fig. 1;

Fig. 6 is an enlarged detailview, show- 7 ing the bored member of thebarrel;

Fig. 7 is a fragmentary perspective view of one of the reinforcing segments which form part of the cannon;

Fig. 8 is an end View of a modified form of clamp for the barrel segments; and Fig. 9 is a fragmentary view illustrating a wire-bound bored membein' As herein embodied, my invention comprises a barrel consisting of a bored member 10; a plurality of strengthening segments 11, clamps 12 for said segments, and a layer of heat resisting or non-heat conducting material 13 between the segments 12 and bored member 10.

As can be seen in Fig. 6, the bored member 10 is at one end connected to a breech block 14, to which a breech mechanism can be applied if the cannon is to be a breechloader. If the cannon is to be a muzzleloader, the breech mechanism will, of course, be omitted.

The gun is assembled by placing a suitable number of wedge-shaped segments 11 on the bored member 10, said bored member being first covered by a non-heat conducting substance 13, such as asbestos, or a mat or sleeve made of compressed mineral wool. After the segments have been fitted, the twopart clamps '12 willbe applied to the segments and the bolts 16 thereof tightened up to cause the clamps to firmly grip the segments, thereby holding them in place.

The cannon will now appear as illustrated in F ig, 1, where the segments 11 are shown as having stepped parallel surfaces 16*. The segments may, however, hewe tapering stepped surfaces, as indicated by 17 in Fig. 2. In this instance the rear clamp 12 is provided with trunnions 18 to engage a guncarriage or suitable" support (not shown). The clamp 12 will of course be provided with a bore to fit the horizontal surfaces 16 of the segments 11, while the bore of the clamp 19 will be tapered to fit the tapering surfaces 17 of the segments 20 which go to make up the cannon, as illustrated in Fig. 2. The bored member 10 will be the same in all the forms of my improved gun.

To prevent the clamps from slipping after they have been applied, I prefer to provide he'bo're d member 10 may Copies; of this patent may be obtained for said clamps with teats or projections 21 arranged to enter recesses 22 in two (in this instance) of the segments 11 (Fig. 5) The clamps 19 will be provided with similar teats or projections to engage recesses in some of the segments which go to make up the can non illustrated in Fig. 2.

be a plain tubular member or a tubular member reinforced by Wrapping wire (indicated by 23, Fig. 9) therearound. It will be apparent that,sin

the arrangements shown in Figs. 1 and 2, each stepped section of the assembled segments will have its own clamp; but I may employ clamps 2a (Fig. 8) having a bore 25 to fitthe last stepped section, or the breech section, of the segments and provide fillers 26, 26, 27, 27, and 28, 28, whereby any one of theclamps can ber'nade to "fit any one of the stepped sections of the assembled segments by fitting the bore 25 with the proper fillers For instance, the clamp 24, having all the fillers, can be applied to section A, Fig. 1; the clamp having the fillers 26, 26, and'27, 27, will fit section B; the clamp having only the fillers26', 26, will fit section C, While the clamp which has no fillers at all Will fit the breech section.

The formof cannon-illustrated in Fig. 3 consists of a bored member 10 (Fig. 4) the same as in the other forms, surrounded by a layerof non-heat conducting material and segments 29 which are tapered but not stepped." To reinforce the segments 29', also to hold them in place, I provide sleeves 30 having tapering bores to fit the tapering outer surface of the segments 29. The sleeves 30 are held in place by rods 31 passing through ears 32 having slots 33 to receive the rods 31. The rods'31 are threaded at at to receive 'nuts 35 which will bear against the ears 32. After the sleeves have been slipped onto'the segments, when assembling the gun, the rods 31 will be slipped into the slots 33 and the nuts 35 screwed up to draw the sleeves'toward thebreech of the barrel,

whereby the segments 29 will be firmly held in place. It will be noted that the sleeves 30 Will be drawn up by the nuts independently of'each other. The breech-block 1 1 carries cars 36 to act as an abutment for the heads 37 of the rods 31. Both the breech clamp 19 inl the form of cannon illustrated in Fig. 2, and the breech-sleeve 30 in the form illustrated in Fig. 3, carry trunnions 38, and 39,

respectively, to engage a gun-carriage or a day of March, 1918.

suitable support. The segments in all the forms materially reinforce the bored barrel member without materially increasing the weight of the cannon, the clamps acting to reinforce the segments. The sleeves 30 do not need any means other than the nuts 35 to hold them in place.

Instead. of employing the clamps shown and described, I may detachably hold the segments together by means of chains or other holding means. I I

For small caliber guns, he Wedge sections 16, 17 and 29 may be made of hard Wood or other light material, the lining 13 of heat resisting material acting as a protector.

What I claim as my invention is? 1. A'cannon, consisting of a bored barrel inember, segments surrounding said barrel carried by said sleeves provided with slots,a

rod arranged to be slipped into said slots, said rod being threaded adjacent said ears, nuts carried by the threaded portions of the rod, to force said sleeves toward'the breech of the cannon, and means to" anchor one end of said rod. I

3. A cannon, consisting of a bored barrel member, segments surrounding said barrel to reinforce same, said segmentshaving a tapering outer surface, sleeves having a tapering bore arranged to be slipped over said segments in spaced apart relationship, to secure same in position, and securing means common to all the sleeves, to force said sleeves toward the breech of the cannon, independently of each other.
